John La Farge was an American artist whose career spanned illustration, murals, interior design, painting, and popular books on his Asian travels and other art-related topics.
La Farge is best known for his production of stained glass, mainly for churches on the American east coast, beginning with a large commission for Henry Hobson Richardson's Trinity Church in Boston in 1878, and continuing for thirty years. La Farge designed stained glass as an artist, as a specialist in color, and as a technical innovator, holding a patent granted in 1880 for superimposing panes of glass. That patent would be key in his dispute with contemporary and rival Louis Comfort Tiffany.
La Farge rented space in the Tenth Street Studio Building at its opening in 1858, and he became a longtime presence in Greenwich Village. In 1863 he was elected into the National Academy of Design; in 1877 he co-founded the Society of American Artists in frustration at the National Academy's conservatism. In 1892 La Farge was brought on as an instructor with the Metropolitan Museum of Art Schools to provide vocational training to students in New York City.
